J-PARC is a new high-intensity proton accelerator research facility in Japan. It has a spallation neutron source that will produce the world highest intensity pulsed neutron. It is expected that high pressure material science and the investigation of the Earth's interior will greatly improve at J-PARC. A Paris-Edinburgh cell and a cubic anvil high pressure apparatus have been brought to an Engineering Materials Diffractometer(BL19) to conduct the first high pressure experiment. As the next stage, we are planning to construct a dedicated high pressure beamline that will open in 2011.
